Document Summary
A large number of pgcs (now named oocytes) will die. Whereas in male they will continue to divide. Squamous granulosa in clusters (cysts) surrounded by the squamous granulosa. Oocytes start meiosis and arrest in prophase i. Happens before parturition or right after parturition. The maximum number of follicle that a female can have, this can be used to predict the reproductive potential. Rodents: cluster (cysts) assembly occurs at birth. In humans and cows, this process occurs mid gestation. Cysts break down and oocytes surrounded by a layer of cuboidal granulosa cells (assembly) = primary follicle. Primordial follicles do not proliferate, population represents a female"s total reproductive potential. Once stimulated into a primary follicle the process is irreversible. This process results in significant oocyte death = critical stage. Process of primordial follicle formation is gonadotropin (lh, fsh) independent in mammals. In vitro, most primary follicles do not arrests in prophase i. Define by a simple cuboidal cells surrounding the oocyte.
